. In Fig. 1 of the drawings there is illustrated in perspective anironing apparatus of the roll 30 type which includes a support 20, atransmission indicated generally at 22, an ironing roll 24 supportedfrom the housing oi the transmission 22, an ironing shoe 28 mounted uponan arm 28 carried by the support 20, a control member 30 35 which isoperable for controlling the operation of the ironing apparatus and asecond control member 32 which is operable for changing the speed atwhich the roll is driven, or for disconnecting the roll from its drivingmechanism so 40 that the ironer may be operated for pressing.

The transmission 22,'as illustrated, comprises a housing which includesan open-ended supporting member 3! rigidly secured to the support 10 inany suitable manner, a bearing plate 36 ior closing the end of thecompartment 38 within the housing within, which the transmission mechanism is disposed, said bearing plate being detachablyand rigidlysecured to the end iace'oi the support member 34 such as by a pluralityof bolts 40, and an ornamental cap 42 which is adapted to cover thebearing plate 36. The ornamental cap 42 may beheld in place by a plu-vrality of springclips carried thereby and which are engageable withapertured portions of the bearing plate 36. The housing of thetransmission may extend below the surface of the support or table 20 toprovide a space or compartment 46 open at the bottom end in which amotor 48 for operating the ironer may be arranged. The motor 48 may besupported by the housing in any suitable or convenient manner.

The shoe 26 preferably is provided with a heating means therein andincludes a polished metallic face 50 which is shaped to conform to thepadded surface of the roll 24 and is coextensive in length therewith.The shoe 26 is carried by the arm 28 of a channel shaped bell cranklever 54 and to the upper end of which arm 28 the shoe is connected bymeans of a pivotal connection 56. The pivotal connection may include ahorizontally disposed pin 58 passing through aligned openings in theupper end of the arm 28 and in a bracket 60 carried by the shoe 26. Aspring clip 62 carried by the pin 58 has one end thereof engaging aportion of the shoe at 64 and the other end thereof engaging a portionof the arm 28 at 66 forflresiliently supporting the shoe from the arminthe position illustrated in Fig. 6. The

arm 28 of the bell crank extends upwardly through the opening at therear of the support 20 and midway between the ends of the roll 24. Thesupport 20 may be provided with a pair of spaced downwardly extendingbrackets 68 carrying a pin I0 on which the bell crank lever 54 ispivotally supported by means of a hub 12 formed integrally therewith.That portion of the bell crank 54 below the surface of the support 20extends horizontally and may be bifurcated to provide a pair of arms I4.Each arm I4 has associated therewith a coil spring 84 backed up by anadjustable, seat I6 provided by a washer held against upward movement bya nut 18 threaded on to a fixed post secured to a bracket 82, forresisting clockwise movement of the bell crank 54 about its pivot I0. Apair of nuts 86 may be threadedly secured to the bottom end of each post80 and below each of the arms I4 to provide a stop for limiting thecounter clockwise movement of the bell crank 54 about its pivot I0. Thespring 84 provides a resilient stop for the shoe 26 and is adapted topermit movement of the shoe 26 relative to the roll 24 when the partsare in the position illustrated in Fig. 6 so as to accommodate materialof substantial thickness between the surface of the padded roll 24 andface 50 of the shoe 26.

While the shoe is adapted to remain substantially in the positionillustrated in Fig. 6 or 7, the pivotal connection 56 between the shoe26 and its supporting arm 28 is such as to permit the shoe to be turnedin a clockwise direction about the pin 58 to a position where the faceof the shoe is disposed upwardly or in a substantially horizontalposition so as to permit the shoe to be used for steaming purposes. Thepivotal connection 56 between the shoe 26 and its supporting arm 28 alsois such as to permit a slight amount of turning of the shoe 26 about avertical axis in order that the face of the shoe may be properly appliedto the surface of the padded roll 24 particularly under conditions wherematerial is being passed between the shoe and the roll only at one endthereof. As the shoe is supported from a point centrally of the endsthereof, the pressure between the face of the shoe and the surface ofthe padded roll will be distributed substantially equally over theentire contacting surfaces.

The roll 24 may comprise a cylindrical metallic shell 88 coveredsubstantially by padding 90 of substantial thickness and a smooth pieceof fabric 92. One end of thelroll may be provided with a circular plate94 having the outer periphery thereof flanged at 96 and welded orotherwise secured to the inside of the shell 88, while the center of theplate 64 may be flanged inwardly at 98 to provide a seat for a bushingI00 which is secured to flange 98 and is supported for rotation on abearing I02 by'means of which one end of the roll is supported. Thebearing I02 is provided by one end of a plug, the other end of which isseated within the end of a tube I04 and fixed thereto. A collar I06 anda nut I08 threaded into a suitable opening in the plug I02 may beutilized for preventing axial separation of the bushing I00 and bearingI02. The tube I04 extends along the axis of the roll 24 andapproximately the length thereof. To the other end of the tube I04'(Fig. 4) there is fixedly secured a circular plate IIO, the outerperiphery of which is flanged to provide an annular bearing II2 whichforms a seat for an annular bearing member II4 carried by the roll 24adjacent the transmission end thereof. The tube I04 is heldagainst'rotation, as will be hereinafter explained, and the roll 24 isadapted to rotate upon the tube I04 and the bearings provided thereby.

The housing of the transmission, as illustrated in Figs.2 and 4, isprovided with an annular boss II6 which forms a socket or rigid seat fora supporting tube II8, one end of which may be press fitted into thebore of the boss II 6 and locked therein by means of a set screw I20.The outer end of the tube II8 which may terminate substantiallycentrally of the ends of the roll 24 and is adapted to provide a bearingseat I2I for an arm or member I22, the lower part of which is arrangedto telescope the end of the tube H8 and the upper part of which may bebifurcated as at I24 and which bifurcations are provided with alignedbores I26 for receiving the tube I 04 and which tube I04 may be lockedto the arm I22 by means of a pair of set screws I28. While the arm I22is locked to the tube I04, the arm I22 is free to oscillate about thetube II8.

A roll oscillating tube I 30 extends through the tube H8 and at one endthereof is seated within a bore in the arm I22 and locked thereto bymeans of a set screw I32 while at the other end. said oscillating tubeI30 is seated in a bushing at I34 arranged within the end of the tube II8. The tube I30 is adapted to be oscillated, as will hereinafter beexplained, for moving the roll 24 toward and away from the shoe 26.;While the roll will rotate about the axis of the tube I04, theoscillation of the roll about the axis of the tube I30 will cause thesurface of the padded roll 24 to move into and out of engagement withthe face of the shoe 26.

A roll driving shaft I36 extends axially of the tube I30 and at one endthereof-(Fig. 5) is provided with a pinion I38 fixed upon the shaftoperatively engaging an internal gear I40 provided by a member I42 whichis secured to the shell 88 of the roll for movement therewith, such asby means of one or more screws I44. The hub of the gear I40 may-beprovided with a bearing member I46 which may be seated upon the outsideof the tube I04 so that the gear I 40 in effect will rotate upon thetube I04. As the center of oscillation of the roll and the center ofrotation of the pinion I38 coincide, the teeth of the pinion will alwaysbe in driving relationship with the teeth of the gear I40.

The roll oscillating tube I30 extends into the mechanism compartment 38of the transmission housing and has there connected to it a sleeve I46by means of a set screw H8 so that the sleeve I46 will oscillate withthe tube I30. The sleeve is provided with an arm I50 (Fig. 8) connectedby means of a pin the connecting rod I54 being connected to an eccentricI56 rotatable upon apfixed shaft I58. One end of the shaft in the wallof the transmission housing and the other end of the shaft I58 issupported by the bearing plate 36. The eccentric I56 is formed as a partof a membervwhich includes a hub I60 rotatable upon the shaft I58.

A worm wheel I62 (Fig. 2) driven by a worm I64, provided with acylindrical hub I66 (Fig. 4) is rotatably mounted upon the shaft I58.The

I hub I60 of the eccentric I56 and the hub I66 of the worm wheel I62 areadapted to provide 9.

- cylindrical clutching surface for a spring clutch engaged in 8. notchin ates to transmit torque which includes a coil spring I68, one end I10of which is turned radially outwardly to be seated between a pair oflugs I12 provided on a side of the eccentric I56. The other end of theclutch spring I68 is also turned outwardly at I14 and a circular plateI16 freely rotatable on the hub I66 of the worm I62 and held infrictional contact with an annular surface I18 on a side of the wormgear I62. The inside diameter of the clutch spring I68 may be finishedand may be slightly smaller than the 'outside diameter of the hub I66 sothat there is very slight frictional'drag betweenthe two parts duringsuch time as relative movement therebetween takes place. The springclutch including the parts I68, I66 and I comprises a form of a one wayor over running friction clutch and operin one direction only. The plateI16 is provided with a pair of axially extending lugs I spaced degreesapart and adapted to be engaged by an end I82 (Fig. 2) of the controlmember 30..

During such time as the motor 48 is operating, the worm gear I62 will becontinuously driven and the eccentric the control of the spring clutchfrom the continuously operating worm gear I62. As illustrated in thedrawings, the spring clutch including the parts I60, I66, I68, "6 andI82 comprises what is commonly known in the art as an 180 degree clutch,that is, a clutch which will, upon engagement, remain engaged for 180degrees of rotation and thereafter will automatically disengage. In the'case of the spring clutch illustrated herein, the rotation of the wormgear I62 and hub I66 will tend to rotate the plate I16. However, as .theend I82 of the control 30, by engagement with one of the lugs I80 on theplate I16, holds the same against rotation, the spring I68 will not gripthe clutching surface I66 and hence the eccentric I56 will remainstationary. As the spring I68 is coiled in the opposite direction inwhichthe worm gear I62 rotates, rotation of the worm gear I62 will tendto cause the spring I68 to wind up or grip the clutch surface I66 due tothe frictional drag between .the plate Il0and the side wall of gear I62and the inside of the clutch spring I68 and clutch surface I66. Thecontrol member 30 which is pivoted at I84 to a boss on the inside of thetransmission case isadapted upon operation to move the end I82 out fromin front of the lug I80,

I52 to a connecting rod I54,

I58 is seated within a bore oscillate the tube I30, arm I22, tube I56 isadapted to be operated under and 2I8 are mounted thereon therebypermitting the plate I16 to be carried around with the worm gear I02 dueto the frictional drag therebetween. As soon as the plate I16 begins torotate with the worm gear I02, the spring I68 will contract and grip theclutching surface I66, thereby coupling the member I00, and the memberI66 for driving the memberlll and the eccentric I56. The control member00 is adapted to be operated simply by pushing the same and immediatelythereafter releasing it. As the worm gear I62 is rapidly rotating, thelug I00 will begin to move. As soon as the end I02 of the control member30 moves out from in front there- ,of, and as the control member isimmediatelyreleased after actuation, the end I02 thereof will return toa position in the path of the lugs I00, but the lug I80 with which theend I02 was in contact will have been moved around with the gear I62 andthe end I82 of the control 00 will be in the path of the second lug I00upon the plate I16 thereby permitting 180 degrees rotation of the plateI16. So soon as the second lug I00 comes into contact with the end I82of the control .30, the clutch spring I68 will unwind or release itsgrip upon the clutch surface I00 with the result that the eccentric I56will immediately come to rest and the worm I62 will continue to rotate.Upon each actuation of the control 00, the eccentric I56 will movethrough 180 degrees of travel and will through the intermediary of theconnecting rod or link I50 and the sleeve I40 I04 and roll 24 for movingthe roll relative to the shoe.

In the position in which the parts are illustrated in Figs. 3 and 4, theroll is in shoe-engaging position; whereas in the position in which theparts are illustrated in Fig. 7, the roll has been shifted away fromthe.shoe. Upon each successive operation of the control 30, the rollwill be alternately shifted toward and away from the shoe. 8

Referring particularly to Figs. 4 and 6, it will be observed that theworm I64 at its upper end is journaled in a bearing is journaled in abushing I88. The bushing I00 is arranged within a bore formed in a wallI80 of g the transmission housing and the worm shaft is provided with ashoulder I82 which is adapted to be located by means of anut I84threaded into a cooperative part of the wall I80 and rigidly held inplace by means of a lock nut I96. The nut I94 and lock nut I96 provide ameans for properly locating the worm with respect to the worm gear I62.The coupling I88 operatively connects the shaft of the worm to the shaft200 of the motor. The motor 48 may be electrically operated under thecontrol of a mechanically operated switch so that during such times asthe ironer is not in use, the motor may be stopped.

One side of the worm gear I62 is formed to provide a part 202 of a dogclutch which may be referred to as the roll driving clutch. The otherpart 204 of the roll driving clutch is formed upon a hub 206 which isprovided with a pair of gears 208 and 210, the clutch member 204 and thegears 208 and 2I0 being rotatable as a unit. The hub 206 is adapted tobe shifted axially by a fork 2I2 for the purpose of engaging anddisengaging the into the end of the roll oscillating tube I00 and pairof gears 2l6 for rotation relaextends therebeyond where a I86 and at itslower end the roll'driving clutch in engagement.

tive thereto. The gears 2I6 and H0 are in constant mesh with the gears208 and 2I0 respectively, audit will be observed that the size of thegears is such as to provide two different driving speeds for the rolldriving shaft I36. Clutch member 220 slidably keyed to the roll drivingshaft I36 and disposed between the gears 2I0 and 2I8 forms part of a dogclutch which is adapted selectively to connect either the gear m or thegear m to the shaft m for driving the same. Gears 2I6 and 2I8 are eachprovided with a dog clutch member 222 cooperable with the clutch'member220 for connecting either of the gears 2I6 or 2I8 to the shaft I36. Theclutch' members 220 and 222, which may be designated as-the two speedclutch are adapted to be opv erated by a fork 224 (Figs. 2 and 6)engageable with the member 220 and slidable upon a rod 226. One end ofthe rod may be provided with a plurality of notches 226 (Fig. 2) and theshift fork 224 may be provided with a detent 230 for engagement with thenotches 228 for locating the positions of the clutch member 220 andholding the in the selected position. The shift fork 224 is"adapted t4:be operated by the control member 32 which isfmounted ,upon a shaft 232(Fig. 6) extending ;through a boss 234 in the front wall'ofthejtransmission housing. Within the same, so. that upon movement of thefinger of the control member 32 to the left from the positionillustrated in Fig. 2, the shift fork 224 and clutch member 220 areshifted to selectively connect either of the gears 2I6 or 2I8 to theshaft I36. One end of the pin 232 may extend into a horizontal slot inthe shift fork 224 so as to provide a guide therefor. In this manner theoperator may select the speed at which the roll will rotate or maydisengage the clutch member entirely so that the roll will remainstationary for pressing purposes or the like.

The shift fork 2I2 (Fig. 4) which is operable for engaging anddisengaging the roll driving clutch 202, .204 is carried by a hub 240fastened upon a slidable rod 242 mounted for axial movement in a pair ofguides 244 formed on the inside of the transmission housing at the topthereof. The shift rod 242 is biased by means of a spring 246 confinedbetween one of the guides 244 and a collar 246 held in place on the rod242 by a pin 250 for holding the parts 202, "204 of The con-. nectingrod or link I54 (Figs. '7 and 8) -is-formed to provide a cam 252 whichisadapted to engage one end of the shift rod 242, upon rotation of theeccentric I56, for shifting the shift rod 242 to disengage the parts202, 204 of the ro'lldriving clutch when the roll is shifted out ofironing relationship with the shoe2 6. The spring 246 operates to e g ethe roll'driving clutch when the cam 262 is moved out of engagement withthe end of the shift rod 242, which occurs when -the roll 24 is beingshifted into ironing relationship with the shoe. Thus the roll drivingclutch is engaged when the ironing roll is shifted into engagement withthe ironing shoe and is disen gaged when the roll is shifted out ofengagement with the ironing shoe. If one of the gears 2I6 or 2I6. isconnected to the shaft I36 through the clutch member 220, the roll 24will be rotated about its own axis when the roll driving clutch isengaged, and the roll will be at rest when the 24 roll driving clutch isdisengaged.

the housing, anarm 2361 is pinned to the shaft 232 and carries a pint;238 which extends into: a vertical slot in the shift fork 224 foroperating In operation, assuming that the motor is operating and thatthe roll is operated from the shoe as illustrated in Fig. 7, material tobe ironed may be laid upon the upper portion of the roll in the propermanner. Operation of the control member 30 will cause the rolloscillating clutch to engage in order to fleet the shifting of the roll24 into ironing relationship with the shoe. As a result of the shiftingof the cam 252 during the shifting of the roll 24 into engagement withthe shoe 26, the roll driving clutch 202, 204 will be engaged and,assuming the clutch member 220 is connecting one of the gears 2I6, 2I8to the shaft I36, the roll will be rotated about its own axis and causethe feeding of the material to be ironed in between the face of the shoeand the surface of the roll. Subsequent operation of the control member30 will effect the shifting of the roll out of engagement with the shoeand will also bring about the disengagement of the roll driving clutch.

If it is desired to use the ironing machine for pressing purposes, thecontrol 32 may be opergaged.

Inthe modified form an... invention illustr'atedin" 9, thesametransmission mechanism, controls and otherparts of the apparatusillustrated in Figs. 1 to 8 may be used, the construction illustrated inFig. 9 differing from that illustrated in Figs. 1 to 8 in the manner inwhich the ironing roll is supported and driven. In this modification atube 3I8 may be rigidly secured within a socket 320 formed in thehousing of the transmission, said tube 3I8 and the wall of the socket320 being provided with an arcuate slot through which a pin 322 extends.The pin 322 at its inner end extends into and fits a hole in anoscillating tube 330 and at its outer end is threaded into a. sleeve 33Iwhich has a hearing on the outside walls of the socket 320. A plate 332is rigidly secured to a radially arranged face-of the sleeve 33I and atits outer end is formed to provide a bearing 333 upon which one end ofthe roll 324 rotates and is supported.

The tube 3I8 extends substantially the entire length of the roll and atits outer end is provided with an internal bushing 334 ,whichforms abearand support at the outer end of the roll upon which is journaled abushing 331 carried by an end plate 338of the roll. The outer end of:the oscillating tube 330 is provided internallywith a bushing 339 whichforms a bearing for the end of a roll driving shaft 340 carrying apinion 3 which meshes with an internal gear 342-connected to the'shellof the roll 324 for driving. the same. In this case the supportingtube 3I0 extends substantially the full length of the roll and the axisof the tube 3I6 coincides with the axis of oscillation of the roll324.The roll driving shaft 340 is disposed upon the axis of oscillation ofthe roll 324 so that the pinion 3 will remain in engagement with theinternal gear 342 at all times. The roll driving shaft 340 and the rolloscillating shaft 330 may be driven or operated as illustrated in theembodiments disclosed in In the modification illustratedin Fig. 10, asupporting tube 350 may be securely seated within a socket 352 formed onthe transmission case with the tube 353 preferably extendedsubstantially the length of the roll and located on the axis of the rollwhen the roll is in ironing relationship with the shoe. The outer end ofthe tube 350 carries an arm 353 which forms a guide and support for theouter end of a roll oscillating shaft 354, the end of the oscillatingshaft 354 being provided with a crank 355 pinned to the shaft 354 andwhich crank 355 carries a bearing 356 similar to the bearing 336 andwhich forms a support for a bushing or sleeve 35'! carried by i the endplate 358 of the roll.

At the transmission end of the roll, there is secured within the endthereof a bearing member 359 which is journaled for rotation upon abearing 360 carried by an oscillating plate 35I which is pinned to andsupported by the oscillating shaft 354. The plate 36! is provided with aslot 362 through which the roll supporting tube 350 extends. The rolloscillating shaft 354 extends through a roll driving tube 363 which isjournaled in a bearing 364 formed in a wall of a transmission case.Within the transmission, roll shifting mechanism like that illustratedinthe embodiments disclosed in Figs. 1 to 8 may be provided foroscillating the shaft 354 in order to move the roll toward and away fromthe ironing shoe. The roll driving tube 363 at one end is provided witha pinion 365 which meshes with an internal gear 356 carried by thebearing member 359 and at the other end the roll driving tube 363 may beconnected to be driven by roll driving mechanism like that illustratedin Figs. 1 to 8 inclusive of the drawings. In this case or in the caseof the embodiments illustrated in Fig. 9, the roll driving tube and theroll oscillating shaft are concentrically arranged and located upon theaxis of oscillation upon the roll while the roll supporting tube 350 isnot so located. The tube 350 may be located upon the axis of rotation ofthe roll when the roll is in ironing engagement with the shoe, althoughthis is not essential.
